How to Really Design a Packer/Stacker South Coast Engineering teams up with Vaccon to develop a packer/stacker that packs and stacks almost 3,500 jars every 20 minutes. The Challenge

The VDF Vacuum Pump features a unique “dirt tolerant” design.

which has its own integral vacuum manifold to make pump-to-cup connections fast and maximizes vacuum flow to each cup to handle the porous tear sheets. A vacuum switch on the manifold monitors all of the suction cups and signals that the cups have a firm grip on the tear sheet,” says Chad Biron, Design Engineer. “The choice for the Vaccon pumps was based on their dirt tolerance and the incredible ease of tool design. All of the components fit together in erector-set fashion on a standard 1.5" x 1.5" aluminum profile. We were under the gun to get this machine shipped early, and within 2 days the design was complete and the components were on our dock.”

The multi-function EOAT handles both slip sheets and wooden frames separately and combined.

The Vaccon Multi-port Vacuum Manifold distributes vacuum to suction cups and maximizes flow to overcome leakage.
